What happened?

Description

In googlepubsub receiver config there is a regex expression that validates subscription name. If subscription name contains colon in project id we got an error. It is possible to create project id with : in GCP.

Steps to Reproduce

1. Create GCP project with : in project id and pubsub subscription.
2. Set subscription name that contains ':' e.g. projects/my-project:test/subscriptions/some-subscription
3. Try to run Otel collector with this setup

Expected Result

Collectors runs normally and messages are processed.

Actual Resul

Got an error "subscription 'some-subscription' is not a valid format, use 'projects/<project_id>/subscriptions/'"

Collector version

v0.128.0

Environment information

No response

OpenTelemetry Collector configuration

Additional context

Are you sure about that @aglipska ?

I just checked and that is not possible:

Edit: Ah, sorry, you mean the project ID. In any case, I don't think it is possible given the official documentation:

A project ID has the following requirements:

Must be 6 to 30 characters in length.
Can only contain lowercase letters, numbers, and hyphens.
Must start with a letter.
Cannot end with a hyphen.
Cannot be in use or previously used; this includes deleted projects.
Cannot contain restricted strings such as google and ssl. We recommend not using strings undefined and null in a project ID.

Yes, I own some projects that contain colon in their id (I think it is not possible to create subscription like that though). It is possible for example for sovereign cloud project ids. E.g. sovereign-cloud-prefix:fh984yr9281-tp

I can confirm that it is possible for Google cloud projects to contain colons in some rare cases. See https://stackoverflow.com/questions/45457604/how-do-i-create-a-domain-scoped-project-on-google-cloud, for example.

(seems so, the above PR would resolve it)

The PR (#43988) is merged; I assume this ticket can be closed.
